Using Fig. 1.1, complete Table 1.1 with letters A-G. Each letter may be used once, more than once or not at all. The table asks for identification of: efferent blood vessel; part of nephron containing cells that respond to ADH; part of nephron where podocyte cells are located; part of nephron containing cells located in the medulla.
Describe and explain how the cells of the proximal convoluted tubule are adapted for selective reabsorption.
Fig. 1.2 shows the concentration of ADH in the blood at different percentage changes in water potential of the blood. Describe the trend shown in Fig. 1.2.
A person may sometimes have a low concentration of ADH in the blood even when there is a change in water potential. Suggest one effect on the circulatory system of a low concentration of ADH in the blood.
